  • Patent number: 11662027
    Abstract: One or more techniques and/or systems are disclosed for mitigating fluid loss or leakage from a fluid pump with a rotating shaft driving a pumping mechanism. A packing gland component can have an internal seal formed by two dynamic O-rings that allows for use of lubricants at high pressures, as well as an outer seal for greater prevention of fluid loss. Further, the packing gland component can be a retrofit for existing packing gland components to provide for greater life and efficiency as compared to the existing packing gland components. Additionally, in some implementations, a sleeve may be fixedly attached to the rotating shaft between the packing gland and the shaft to provide a wear point for the packing gland.
    Type: Grant
